Below are four factors that could affect a population. indicate 'yes' if the factor could alter allele frequencies, or 'no' if it would not alter allele frequencies in the population. group of answer choices
a. genetic drift
b. natural selection
c. gene flow
d. mutation

a) genetic drift -  yes

b) Natural selection -  yes

c) Gene flow -  yes

d) Mutation - yes

Explanation:

factor that alter the allele frequencies are

a) genetic drift -  yes

b) Natural selection -  yes

c) Gene flow -  yes

d) Mutation - yes

Genetic drift -  Alter occur due to sampling error or selecting error. in this  some error occur while deciding for the allele for the next generation.

Natural selection - it is due to large number of one type of allele in the population

Gene flow - it alter because of migration of allele among the populations.

Mutation  -  it is strong for introduction of new alleles in the population

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
